Singapore's rail network has six colour-coded MRT lines — the North-South Line, the East-West Line, the North-East Line, the Circle Line, the Downtown Line, the Thomson-East Coast Line — plus three LRT loops feeding the suburbs, covering 146+ stations in all. Each station carries a letter-number code (such as NS24 for Dhoby Ghaut); where two codes meet, you can change lines. New to reading it?
